Great Dark Spot
Researchers found that Titan's ice shell, which overlies a very salty ocean, varies in thickness around the moon, suggesting the crust is in the process of becoming rigid.
Artist's Rendition of Titan's Ice Shell
In this movie from NASA's Cassini spacecraft, the gravitational pull of Saturn's moon Prometheus creates patterns in Saturn's F ring. This movie also happens to show a small trail of icy ring parti...

Each of these two montages shows four synthetic views of Titan created using data acquired by the visual and infrared mapping spectrometer (VIMS) on board NASA's Cassini spacecraft between 2004 and...
Working Toward 'Seamless' Infrared Maps of Titan
On May 12, 2007, Cassini completed its 31st flyby of Saturn's moon Titan, which the team calls T30. The radar instrument obtained this image showing the coastline and numerous island groups of a p...

Saturn's moon Pan, orbiting in the Encke Gap, casts a slender shadow onto the A ring. For a closeup view of the "flying saucer" shape of Pan (28 kilometers, or 17 miles across), see Saturn's Sauce...
Shadow of Saucer-Shaped Moon
Saturn's F ring, which appears kinked and gored in many images, looks straight here. Above the brighter core, the ghostly strands of the F ring's outer envelope, which has a spiral arm structure, a...
Straightening Out the Kinks
The bright arc within Saturn's G ring is shown truncated by the shadow of the planet at the bottom of this image.

This is an artist concept and movie of the view from Cassini during the star occultation that detected "Mittens," the small object to the right of the star. As Cassini watched the star pass behind ...
The Huygens probe descends through Titan's murky, brownish-orange atmosphere of nitrogen and carbon-based molecules, beaming its findings to the distant Cassini orbiter. The probe is equipped with...

Cassini bids farewell to Saturn’s yin-and-yang moon, Iapetus. This image is from the last set of observations Cassini made of this world of striking contrasts.
Farewell to Iapetus
The most visually striking feature on Saturn’s icy moon Tethys is Odysseus crater.
Saturn's dynamic F ring contains many different types of features to keep scientists perplexed.

Seasonal changes in the atmosphere of Saturn's largest moon are captured in this natural color image, which shows Titan with a slightly darker top half and a slightly lighter bottom half. Titan's ...
Two Halves of Titan
As seasons change on Saturn, and sunlight creeps farther north, the region surrounding the north pole is steadily coming to light. This scene reveals many features in Saturn's dynamic and beautifu...
Coming to Light
Cassini peeks at Saturn's relatively dark south pole, providing an up-close look at the haze-free upper atmosphere there. The banded structure around the pole seems to be superimposed on the chara...

Enceladus looks as though it is half lit by sunlight in this view from NASA's Cassini spacecraft, but looks can be deceiving.
Dark Side of the Moon: Enceladus
Cool and icy Dione floats in front of giant Saturn bedecked in a dazzling array of colors. The surface of Dione, which exhibits contrasting bright and dark areas when viewed up close, appears pale...
This image shows an updated map of Saturn's icy moon Enceladus, generated by the Cassini imaging team. The map incorporates new images taken in 2008, with better image processing techniques. Comp...
